Life Cycle Analysis

OCTAL is the largest integrated PET sheet and resin manufacturer in the world and the maker of DPET™, a high performing plastic with the lowest carbon footprint on the market today. By producing a superior material with a smaller environmental impact, and using patented technologies that continue to advance innovations in PET processing, OCTAL is driving sustainability in clear rigid plastic packaging.

OCTAL PET Resin - A Low Carbon Alternative

OCTAL has implemented a state-of-the-art two-stage reactor system to produce virgin PET resin. OCTAL’s unique resin manufacturing process eliminates an entire step, SSP, from the standard process, which decreases manufacturing energy consumption. OCTAL bottle grade PET resin also offers superior product performance — exceptional gloss, clarity and consistency — when compared to traditional PET resins.

Life Cycle Analysis

An independent Life Cycle Analysis* conducted for OCTAL found that when compared to PET bottle-grade resin, the production of OCTAL PET resin:

  • Consumes 63% less purchased electricity

  • Uses 23% less on-site thermal energy 

  • Creates a 10% lower cradle-to-gate global warming potential compared to bottle-grade PET

  • Generates a 22% lower cradle-to-gate environmental footprint compared to bottle-grade PET


*The study conducted by Intertek Expert Services used CML 2 baseline 2000 methodology to compare the environmental impacts of 1 kilogram of OCTAL’s PET resin made at the Salalah, Oman, facility from cradle-to-gate with traditional bottle-grade APET (including all steps up to the point of production). 

OCTAL resin is highly efficient in injection molding and extrusion applications, allowing customers to reduce their energy use. In addition, customers using OCTAL PET resin can operate with a faster cycle time because our spherical shaped resin allows for more even heat dissipation and eliminates surface dust formation. This allows customers to reduce their own electricity requirements and processing carbon footprint.

OCTAL DPET™ Sheet: Smaller Carbon Footprint

OCTAL’s Direct-to-Sheet PET, or DPET™, is the first and only direct-to-sheet polyester sheet in the world. Through the use of pioneering technology, OCTAL’s manufacturing process consumes less energy and creates a smaller carbon footprint than comparable products. OCTAL’s unique direct-to-sheet process, eliminates five energy-intensive stages of the conventional sheet production process — pelletizer, solid state poly condensation (SSP), compactor, dryer and extruder. This dramatically decreases energy consumption while increasing efficiency. Independent studies commissioned by OCTAL have shown that DPET™ has a significantly lower carbon footprint than competing products. The finished product can achieve additional environmental benefits through downgauging of up to 10%, allowing OCTAL customers to use less DPET™ to produce an equivalent or superior product. The post-production waste generated from DPET™ is also nonpareil, facilitating easier recycling.

Life Cycle Analysis

Results of a study* comparing different types of plastic showed that OCTAL DPET™ sheet has a lower environmental impact than APET. Specifically, when compared to the traditional APET process, DPET™ sheet:

  • Consumes 65% less purchased electricity

  • Uses 28% less on-site thermal energy

  • Creates an 18% lower global warming potential

  • Generates a 30% lower cradle-to-gate environmental footprint

The study conducted by Intertek Expert Services used CML 2 baseline 2000 methodology to compare the environmental impacts of 1 kilogram of OCTAL’s DPET™ sheet made at OCTAL’s Salalah, Oman, facility from cradle-to-gate (including all steps up to the point of production) with traditional APET.

In studies conducted by Intertek Expert Services, OCTAL’s DPET™ sheet outperformed both virgin PET and recycled PET in Scope 1, 2 and 3 emissions, making it the least carbon intensive PET sheet on the market.
